The satellite also featured a slow-scan TV camera (100 lines per frame, 10 frames per second), which relayed images to the ground.

There was also a spectrophotometer for UV (1216 A) and Soft-X-rays (1-120 A) using a photomultiplier tube and a filterwheel. This instrument sent data through a commutated telemetry channel. The instrument was designed by the St. Peterburg physicist A. Jefremov under the direction of Academicians A. Lebedev and S. Mandelstam.
